Actually, 2.0.0.3 didn't fix it because that was the only version of winpwn I've ever used. So this is just a work around until it's really fixed. Most people probably already have SP3 if they have automatic updates on.

WinPwn crashes shortly before coimpleting the build of the custom ipsw file. Dumps and drashes out.

Windows XP SP2.

I had tried xWinPwn before and that worked for me, cydia also worked but then I installed a bossprefs update which put the ipod into a state of getting very hot whilst showing the apple logo. Full restore with the original IPSW file was the only way for me to use the ipod again.

Will await the next release of winpwn before going further. I cannot install SP3 for Windows XP as this kills my laptop (BSOD).

I may also try one more time but without the custom logo that I had chosen, although surely that cannot be the cause of the crash.
